What to Do When the Electronically Assisted Steering Wheel Feels Heavy?

[DiChristian]

An electronically assisted steering wheel becoming heavy is mainly caused by insufficient lubrication in the steering gear, low tire pressure, a depleted battery, or a malfunctioning power assist unit. The specific explanations are as follows: 1. Insufficient lubrication in the steering gear: When the car's steering gear lacks lubrication, symptoms such as steering stiffness and a heavy steering wheel may occur. In this case, lubricating oil should be added, and if necessary, the power steering fluid should be replaced. 2. Low tire pressure: When the tire pressure is too low, the contact area between the tires and the ground increases, leading to greater resistance while driving, which makes the steering wheel feel heavier. In this situation, the tires should be inflated promptly. 3. Depleted battery: If the battery is depleted for an extended period, the steering wheel will not receive assistance from the motor. In this case, the battery should be recharged. 4. Malfunctioning power assist unit: If the car's electronic power assist unit fails, a heavy steering wheel can be one of the symptoms indicating a potential issue. For a detailed diagnosis, it is advisable to consult professionals at a 4S shop or a repair facility.
